+# ChecksFinder Randomizer Setup Guide
+
+## Required Software
+
+- ChecksFinder from
+  the [Github releases Page for the game](https://github.com/jonloveslegos/ChecksFinder/releases) (latest version)
+- Archipelago from the [Archipelago Releases Page](https://github.com/ArchipelagoMW/Archipelago/releases)
+    - (select `ChecksFinder Client` during installation.)
+
+## Configuring your YAML file
+
+### What is a YAML file and why do I need one?
+
+See the guide on setting up a basic YAML at the Archipelago setup
+guide: [Basic Multiworld Setup Guide](/tutorial/Archipelago/setup/en)
+
+### Where do I get a YAML file?
+
+You can customize your settings by visiting the [ChecksFinder Player Settings Page](/games/ChecksFinder/player-settings)
+
+### Generating a ChecksFinder game
+
+**ChecksFinder is meant to be played _alongside_ another game! You may not be playing it for long periods of time if 
+you play it by itself with another person!**
+
+When you join a multiworld game, you will be asked to provide your YAML file to whoever is hosting. Once that is done,
+the host will provide you with either a link to download your data file, or with a zip file containing everyone's data
+files. You do not have a file inside that zip though!
+
+You need to start ChecksFinder client yourself, it is located within the Archipelago folder.
+
+### Connect to the MultiServer
+
+First start ChecksFinder.
+
+Once both ChecksFinder and the client are started. In the client at the top type in the spot labeled `Server` type the 
+`Ip Address` and `Port` separated with a `:` symbol.
+
+The client will then ask for the username you chose, input that in the text box at the bottom of the client.
+
+### Play the game
+
+When the console tells you that you have joined the room, you're all set. Congratulations on successfully joining a
+multiworld game!
